BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a rack for holding packs of plastic bags of the type having an upper disposable portion and a lower bag portion. The rack has side protectors which direct a user's attention to the top and center of the front of the bag and significantly improves opening and using the bag.

2. Description of the Related Art

In supermarkets and other retail outlets, there is frequently the need for consumers or store employees to place items in bags to facilitate handling and purchase. For example, produce bags are dispensed directly to customers wherein the customer can bag produce as it is chosen for purchase. Also, in deli or meat departments, store employees place meats and other deli products in bags for the consumer. Further, in bakery departments, store employees place the selected bakery products in bags for the consumer. In the prior art, there are a number of designs for dispensing bags for these purposes.

Roll mounted produce bags are commonly found in modem grocery stores and supermarkets. These bags are designed for customers to use when purchasing fresh produce. The bags currently available are difficult for customers to use for several reasons. First, the bags tend to cling together and are difficult to separate from the roll. Second, it is difficult to tell the open end of the bags from the closed end of the bag. Third, the bags are difficult to open as the sides tend to cling together.

U.S. Pat. No. 5,732,833, commonly owned by applicant, discloses a dispensing assembly for supporting packs of plastic bags. The packs of plastic bags include a disposable upper portion connected to a lower bag portion.

Thus, there are a number of shortcomings with the known rolls of plastic bags and packs of plastic bags. A common problem with bag dispensing systems is presenting a plastic bag in a manner wherein it is easy to open and use.

SUMMARY OF THE INVENTION

Accordingly, a need has arisen for a rack for holding packs of plastic bags where a plastic bag is presented in a manner wherein it is easy to open and use the plastic bag.

In accordance with the present invention, a rack is provided for holding packs of plastic bags, comprising: a back support having two side protectors, a top plate operatively connected to the back support, the top plate having at least one hook designed for holding a pack of plastic bags with the back of a plastic bag against the back support and with the front of a plastic bag facing forward, wherein the two side protectors are designed to direct attention to the top center of the front of a bag such that it is easily opened.

Accordingly, an object of the present invention is to provide a rack for holding packs of plastic bags wherein it is easy to open and use a plastic bag.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

The present invention relates to a rack for holding packs of plastic bags. As discussed further below, with packs of plastic bags, the back sheet of the bag is attached to an upper disposable section with a serrated line while the front sheet of the bag is not attached to the upper disposable section and remains open, although it is not readily visibly apparent that the front of the bag is open. It has been observed that most users of the packs of plastic bags remove a bag from the pack but many times pull a group or bundle of bags from the side at once, creating unnecessary bag waste. The present invention addresses this problem with the installation of side protectors on the rack. The side protectors deter a user from pulling the bags from the side and thus from removing more than one bag from the pack at any given time. The side protectors direct users to the upper center of the bag which is pre-open, allowing for single bag dispensing. The preferred method of using a bag is first to open the bag by pulling down on the open front sheet such that it separates away from the back sheet which is connected to the upper disposable section, placing product in the bag, and then tearing the back sheet at the serration to remove the bag from the pack.

The user can also pull off the bag from its open front first, and then proceed to fill it up while keeping the bag open on one hand. Preferably, instructions are printed on the front sheet to instruct the user to pull down on the front sheet to separate the front and back sheets, thereby opening the bag.

With reference to FIG. 1, a rack 10 is shown having a back support 11, side protectors 16, and a back support wire 15 which connects the back support 11 with a top plate 12. The top plate 12 is oriented in a vertical position. Preferably, the top plate 12 has two hooks 13 for holding the packs of plastic bags. The hooks 13 are preferably 8 inches apart, but could be set at any distance, e.g., 6 inches. Less preferably, the top plate 12 could have one hook 13.

The back support 11 is shown as five wires connected to a lower portion of the back support wire 15. The back support wire 15 holds the five wires in the correct position. The back support 11 is generally about 3-4 inches in height, but this could vary as desired. While the back support 11 is shown as a wire form, it may be constructed in any suitable way and of any suitable material, such as plastic or acrylic, and it may extend to any height, even up to the top plate 12. The back support 11 and the rack 10 are about 12 inches to 16 inches wide and may be any suitable width.

The side protectors 16 are formed by bending, at right angles, the five wires which make up the back support 11. While the side protectors 16 are shown as wire forms, they may be constructed in any suitable way and of any suitable material, such as plastic or acrylic, and they may extend to any height.

The back support wire 15 serves several functions; first, it is connected to the five wires in back support 11 to hold these wires in place. Also, it connects the back support 11 with the top plate 12.

The top plate 12 extends nearly the width of the rack 10 and serves several functions. First, the top plate 12 is connected to two hooks 13 which support the packs of plastic bags. Also, via the back support wire 15, the top plate 12 is connected to the back support 11.

In FIG. 1, the rack 10 further comprises at least one mounting hole 38 in the plate 12 (here, plate 12 is vertically oriented) for mounting the rack 10 to a surface. Preferably, the rack 10 should be mounted such that the rack 10 is placed about waist high. The rack 10 can be located in any suitable location. Placing the rack 10 at about waist height further encourages a user to use the invention in the preferred method, which is first to open the bag by pulling down on the top center of the open front sheet such that it separates away from the back sheet which is connected to the upper disposable section, placing product in the bag, and then tearing the back sheet at the serration to remove the bag from the pack.

The hooks 13 are generally constructed from a plate or wire bent into a U-shape. Preferably, there are a pair of hooks 13 spaced 8 inches apart.

A front extension 19 and a front rail 35 further serve to direct a user's attention to the top center of the front of the top plastic bag. The front extension 19 is formed from the five wires which make up the side protector 16. Here, the wires are bent at nearly right angles. The front rail 35 is connected to the ends of the five wires.

A front extension 19 and a front rail 35 further serve to prevent the removal of more than one bag and direct a user's attention to the top center of the front of the top plastic bag. The front extension 19 is formed from the five wires which make up the side protector 16. Here, the wires are bent at nearly right angles. The front rail 35 is connected to the ends of the five wires. The front extension 19 may be constructed in any suitable way and of any suitable material, such as plastic or acrylic, and may extend to any height.

A side rail 36 extends from the top wire to the bottom of the side protector 16. This side rail 36 serves several purposes; first, it is connected to each of the five wires in the side protector 16 to strengthen the side protector 16 and keep the wires in alignment. Also, it serves to deter a user from attempting to grasp a plastic bag from either side.

FIG. 2 shows a second embodiment of the rack 10. Here, the top plate 12 is positioned horizontally. Additionally, a back support plate 15 is used in place of back support wire 15 of the FIG. 1 embodiment. Further, this embodiment includes at least one support leg 39. The horizontal top plate 12 and support legs 39 are designed to fit over a “produce box” which is a wooden box filled slightly below the top of the wooden frame. The wooden frame is typically 1-2 inches thick. The support legs 39 may be mounted to the wooden frame by utilizing mounting holes 38.

FIG. 3 shows a third embodiment of the rack 10. Here, the top plate 12 is positioned between the horizontal and vertical positions. This embodiment is used when the side walls of the produce box are at an angle at about 45°.

The rack 10 may be constructed of any suitable materials including, for example, stainless steel, plastic, or acrylic. Additionally, different parts of the rack 10 may be constructed of different materials.

The rack 10 is advantageous in that it takes up a minimal amount of space and is inexpensive to fabricate.

FIG. 3 shows a pack of plastic bags 20 wherein a number of individual bag units are joined together to form the pack 20. The individual bag units have a disposable upper portion 21 and a lower bag portion 22 with a serration 23 between the disposable upper portion 21 and the lower bag portion 22. In forming the pack 20, the individual bag units are stacked on top of each other, and a header 24 is placed about the disposable upper portion 21. The header 24 is formed by cutting a flat, generally rectangular plastic piece and folding the rectangular plastic piece longitudinally in half to substantially cover the disposable upper portions 21. FIG. 3 shows one embodiment of the header 24 wherein tabs 26 are cut from the header 24 (prior to folding the header 24 in half) and side holes 27 and center whole 28 are placed in the tabs 26. The tabs 26 are cut from the header 24 at 8 inches, 6 inches or any other suitable distance. The header 24 and the disposable upper portions 21 are joined together in any suitable way; preferably, the header 24 is joined to the disposable upper portions 21 by inserting heated blunt rods through the header 24 and the disposable upper portions 21 to melt the header 24 and the disposable upper portions 21 together about the points of insertion 25. The insertion of the heated blunt rods serve to melt the plastic immediately adjacent to the header 24 and the disposable upper portions 21 at the points of insertion 25 to join together the header 24 and the disposable upper portions 21 of the individual bag units. U.S. patent application Ser. No. 10/814,469, hereby incorporate by reference, discloses other means to fabricate packs of plastic bags and other header designs. For example, the header 24 can be perforated with holes at 8 inches, 6 inches or any other suitable distance. Also, the bags can be attached to paper headers and stapled together.

The individual bag units generally include a back sheet and a front sheet which are sealed around the sides and bottom to form the lower bag portions 22. The back sheet includes serration 23 and the disposable upper portions 21, while the front sheet terminates just below serration 23 to form a bag opening 31. The individual bag units formed with opening 31 allows a product to be placed in a bag while the bag remains attached to the pack of plastic bags 20 such that the user may then use two hands to remove the bag from the pack of plastic bags 20 and seal the bag. The individual bag units are most easily opened by pulling downward on the top center of the front sheet while the back sheet remains attached to the pack.

The material used to create the plastic bags may be any suitable plastic resin, including: low density polyethylene; linear low density polyethylene; high-density polyethylene; high molecular weight, high-density polyethylene; and polypropylene. The plastic film used to create the plastic bags may be either a single extruded layer or multiple, coextruded layers.

All patents referred to herein are hereby incorporated by reference in their entireties.
